I have 9 pages of apps... My lock button is messed up, sometimes when i press it, it doesn't work... Sometimes when i do press it, it does work... I have no clue why, it cant be a hardware issue because it works sometimes. But i did drop it and it didn't work after that... For now its working, but i know it wont in a while. Should i restore? Software or Hardware issue, cause if Hardware how could it only work "sometimes?"
